PATENTl orFics amsn enrosroann 'rms Irvin B. Kaiser, Lyons, N. Y. Application'June 16, 1936, -Serial No. 85,585 2 Clam (Cl. .H2- 178) The object of this invention is to provide a new each of 'the removable rings with a wire cabley that will keep them from stretching and better `hold them in place.

'Ihese and other objects of the invention will l5 'be illustrated' in the drawing, described in the speciilcation, and pointed out in the claims at the end thereof.

In the drawing: Figure l is a top plan view of the tire, showing zo four ribs, each of which is aremovable ring.

Figure 2 is a.. section through the tire on the line 2me- 2x of Figure 1.

Figure 3 is a section through the tire on the line Sav-3x of Figure 1.

I vFigure 4 is a section through the tire' similar to Figure 3, but modiiled by the insertion oi metal ,studs to make the tire antiskid, the section line teing shown at la7-4x of Figure 5.

Figure 51s a top plan view of a portion of the so tire provided with the studs shown in Figure 4.

In'the drawing like reference 'numerals indicate like parts. V

In. the drawing reference numeral I indicates vthe body of the tire, which in this case is covered with rubber in the usual mannerand is formed with four annular grooves 2, l, I, and I. These grooves are enlarged vwith semicircular recesses l, 0, at the sides thereof, as shown-in Figure 1.

In these grooves are placed rings of rubber 4o which extend completely around the tire, these rings 4being indicated by the numerals 1, l. 9 and 4il. At regular intervals on these rings are formed l l semicylindrical projections' Il, I I, these being arranged in pairs opposite to each other. The bodv of the tire has corresponding recesses formed on each side of each of the grooves to receive these projections on the rings.

In each ring there is a reinforce or wire cable, as indicated at i2, I2, which keeps the rings from l0 stretching. l. The tire is deflated and these rings are put in place in the grooves in the tire, and the tire is 'then inilated and the rings sink into the grooves and take iirm hold therein, and thereby form ribs on the tire. When these ribs wear down, the tire can be deiiated and therings can be removed and new rings can be put in place thereon.

In Figure 4 I have shown metal sockets i5 5 formed in the rings, preferably in the semicylindrical extension so that they will be out of the way of the wire cables I2, i2. These metal sockets are threaded with a female thread, and when it ls desired to :nake the tire antiskid, studs I6, i6

can' be inserted in these sockets. These studs will appear as shown in top plan view in Figure 5.

If the tire is punctured and goes at the rings will'have the same tendency to remain on the tire that the tire has to remain on the rim of the wheel. In fact, it is believed that the rings will adhere to the tire..0r stay in place thereon, even more/firmly than the'tire will remain 'on the rim, for the reason that the rings are reenforced s and this would tendor help to restrain them from 42i) 'jumping out of the grooves.

n is obvious that .me rubber rings :hay be omitted and the tire with the annular grooves and semi-cylindrical extensions on the sides of the grooves may be used without the rings. This is 2o `important because in the event that the rings wear down to the surface f the tire, the rings can be re ved and the tire with its empty grooves can be used and forms in itself a new type of non-skid tire.

I claim:

1 A pneumatic tire having a body portion with a plurality of annular grooves therein, a rubber ring placed in each of said grooves and extending above the periphery of the tire, each of said rings 85 having semicylindricai extensions on the sidesr thereof extending from the top to the 'bottom of 'the ring, corresponding recesses in the bodyof the tire in which said extensions engage each of the grooves having a rectangular cross section of and each of the rings having a rectangular cross section that fits lthe grooves, said "grooves and rings running continuously around the tire.

2. A pneumatic tire having a body portion with a -plurality of annular grooves therein, each of said grooves having a rectangular cross section', each of saidgrooyes having semi-cylindrical recesses or extensions on the sides thereof, each of said grooves being adapted to receive a ring havlng a cross section that fits the groove, said tire 'v being capableof vuse without the rings.
